A hypothermic person should be rewarmed gradually using dry blankets and warm fluids. Rapid warming can cause shock.

Carbon monoxide poisoning prevents oxygen from binding to red blood cells, leading to suffocation and organ failure.

Frostbite should be treated by gradually warming the affected area using warm water (not hot) and seeking medical help.

Signs of heat stroke include confusion, hot/dry skin, and rapid pulse. Unlike heat exhaustion, the victim does NOT sweat.

CPR should be stopped only when the person starts breathing normally, emergency responders arrive, or you are too exhausted to continue.

Cleaning the wound with water and covering it with a sterile dressing prevents infection and promotes healing.

If a person is unresponsive and has no pulse, CPR should be started immediately to maintain circulation and oxygenation.

Do NOT push the bone back in. Instead, cover the area with a sterile dressing and immobilize the limb while waiting for emergency help.

Swelling, deformity, severe pain, and inability to move the injured area are signs of a fracture.

Clean the wound with soap and water and seek medical attention, as human bites can introduce harmful bacteria.

Check if the person is responsive. If they are unresponsive, call 911 and begin CPR if needed.

Tilting the head back can cause blood to flow into the throat and airway. Instead, the person should lean forward and pinch their nostrils.

Common symptoms of poisoning include nausea, vomiting, confusion, and difficulty breathing.

FAST stands for Face drooping, Arm weakness, Speech difficulty, and Time to call 911. Recognizing these signs early can save lives.

A person with low blood sugar should be given a fast-acting sugar source like fruit juice or glucose tablets to restore normal levels.

An AED is used when a person is unresponsive and has no pulse. It delivers a shock only if needed.

Inhaling toxic fumes can cause serious respiratory issues, and the first step is to move the victim to fresh air.

Cold water is effective, but ice-cold water or direct ice application can cause further damage to the tissue.

Compressions should be at least 2 inches (5 cm) deep to effectively circulate blood.

Asthma inhalers should be used when symptoms appear, not only when a person is unconscious. Delaying treatment can be dangerous.

Pinching the nostrils and leaning forward helps stop bleeding while preventing blood from flowing into the throat.

Never place anything in a person's mouth during a seizure. Instead, clear the area around them and let the seizure pass.

Installing carbon monoxide detectors in homes and ensuring proper ventilation helps prevent CO poisoning.

Agonal gasps (irregular, gasping breaths) are not normal breathing. CPR should be started immediately.

Applying firm, direct pressure is the most effective way to stop bleeding from a deep laceration.

During a seizure, keep the person safe by clearing the area and placing them on their side to prevent choking. Do NOT hold them down.

Carbon monoxide is a colorless, odorless, and tasteless gas, making it extremely dangerous.

Laying the person flat and elevating their legs improves circulation and helps restore normal blood flow to the brain.

Running cool (not ice-cold) water over a minor burn for several minutes helps reduce heat and prevent further tissue damage.

Human bites can be more dangerous than animal bites because they often introduce harmful bacteria, leading to infection.

Never remove an embedded object from a wound. It may be stopping severe bleeding. Apply pressure around the object and seek emergency care.

A second-degree burn should be cooled with running water, covered with a clean bandage, and left undisturbed to heal.

Installing carbon monoxide detectors and ensuring proper ventilation can prevent dangerous CO buildup.

CPR is only performed if a person is unresponsive AND not breathing. If they are breathing, monitor them until help arrives.

You should always handle a knocked-out tooth by the crown, NOT the root, to protect its delicate tissues for reattachment.

If you suspect a heart attack, the first step is to call 911 immediately. Early treatment can prevent serious damage or death.

To check if someone is breathing, look for chest movement, listen for breath sounds, and feel for air movement on your cheek.

A person in cardiac arrest will be unresponsive, have no pulse, and will not be breathing normally.

Even if a head injury seems minor, delayed symptoms such as confusion, dizziness, or vomiting can indicate a serious problem.

For mild allergic reactions, an antihistamine like diphenhydramine (Benadryl) can help reduce symptoms.

The first priority in treating a deep open wound is to apply direct pressure to control bleeding before cleaning and dressing the wound.

If an allergic reaction affects breathing, administer an EpiPen if available and call 911 immediately.

If a nosebleed lasts longer than 10 minutes, seek medical attention as it could indicate a more serious problem.

A person with a spinal injury should not be moved unless absolutely necessary. Keep them still and stabilize their head and neck.

If an inhaler is not available and the attack worsens, call 911 immediately as it may become life-threatening.

The best way to treat an electrical shock victim is to first disconnect the power source before providing first aid.

The first step is to get the victim to fresh air immediately. Carbon monoxide is dangerous because it is colorless and odorless.

Symptoms of shock include pale skin, weak rapid pulse, nausea, and excessive thirst. A slow, strong pulse is NOT typically associated with shock.

Before assisting a victim, always turn off the power source to prevent further injury.

A hypothermic victim should be warmed gradually with dry blankets and warm fluids, avoiding rapid temperature changes.
